Observations of 23 EC 14026-type pulsating subdwarf B stars

Abstract

Since the discovery of pulsating subdwarf (sdB) stars in 1997 (the EC 14026 class), nearly 40 members have been discovered. After nearly a decade, many of these have had significant follow-up observations to resolve their pulsation spectra and to discern their pulsation properties. In this work we compare and contrast the frequency content in terms of richness and range and the amplitudes and phases for 23 sdB pulsators. We draw no conclusions but merely show the incredible variety of pulsations emanating from seemingly similar stars.
